If they’re TRULY worried about all these experienced bakers and other skilled workers, they’d let them get rehired as NON-union so they could regain their job.
Won’t happen.
Dollars to donuts (or sugary snack cakes), quite a few former union members will be applying as non-union. Such is the case with forced union membership operations - people join only because they have to in order to get the job. Otherwise, they'd likely have avoided union membership.
I worked in a closed-shop union outfit for 11 years. Never really liked the union or what they stood for, but I tolerated it in order to collect a reasonable paycheck.
